In a leaked audio recording that surfaced, Hillary Clinton told supporters in February that she was likely to not sanction the trillion dollar nuclear upgrade project, according The Washington Free Beacon.

According to an audio recording of her comments from a private event in McLean, Virginia., Clinton revealed that she will not go ahead with the upgrade. "I certainly would be inclined to do that," she said when asked about pushing back the Long Range Stand-Off (LRSO) missile program.

The audio, which was from the event attended by campaign supporters, was revealed by hackers who accessed the email account of a campaign staffer, according to the Free Beacon.

The question was asked by former assistant secretary of defense Andy Weber, who was in charge of the Pentagon's nuclear weapons programs. Weber, along with William Perry, who served as secretary of defense under President Bill Clinton, batted for the abolition of the LRSO (Long-Range Stand-Off) program.

"Will you cancel this program if President Obama doesn't in the next 11 months and lead the world in a ban on this particularly destabilizing, dangerous type of nuclear weapon?" Weber asked in the recording.

To which Clinton replied she would be "inclined" to do so. "The last thing we need are sophisticated cruise missiles that are nuclear armed," she said.

The 30-year nuclear upgrade program aims to "modernize" the U.S. nuclear arsenal and build a new generation of weapons and production facilities to last the nation well into the second half of the twenty-first century.

This plan includes redesigned nuclear warheads, new nuclear bombers, submarines, land-based missiles, weapons labs and production plants. The estimated cost of the project is $1 trillion.

Clinton earlier told a peace activist that the planned $1 trillion nuclear weapons modernization program "doesn't make sense", according to The Huffington Post.

Scrapping the program will not go down well with the Obama administration, which is confident of the result and boost for the country.

The State Department has confirmed via emails in response to Freedom of Information Act requests that "Clinton was briefed on aspects of the LRSO debate while serving as secretary of state."

"Do you oppose plans to spend a trillion dollars on an entire new generation of nuclear weapons systems that will enrich the military contractors and set off a new global arms race?" she was asked.

Clinton responded, "Yeah I've heard about that. I'm going to look into that. That doesn't make sense to me."

Meanwhile, former Air Force launch officer John Noonan said he did not agree that Clinton opposed the LRSO program. "There's been tremendous advancements in Russian and Chinese cruise missiles, coupled with an atrophy in American capability," Noonan said.

"The Obama Administration, to their credit, has acknowledged this and have budgeted for the LRSO," he said. "A President Clinton's Pentagon will be faced with the same tough reality."

In response to Clinton's reply to Weber in February, Noonan said she was "just petting a donor on the head and telling him he's pretty."
